Humanistic therapies are often seen as a varient on psychoanalytic therapies similarly to how psychodynamic therapies are seen as a varient on psychoanalytic therapies.

Self Psychology is sometimes regarded as being on the borderline between psychoanalytic / psychodynamic / humanistic.

One way of figuring it out... Might be to look at humanistic therapies (by way of wikipedia or something like that) and to find out who the major theorists are... If you have the luxury of living in a city where there are lots of options it might be possible to pick someone based on their theoretic orientation.

My therapist does a combination of dialectical behaviour therapy / self psychology / family systems therapy. I quite like that :-)
